T0 ctZZ whom it may concern:

Be it known that 1, AUGUST J. VVEIL, a citizen of the United States, anda resident of New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Oar-Axle Bear-'ings, of which the following is a specification.

My invention relates to a certain new and useful improvement in bearingsfor car-axle boxes, and particularly to the construction of the keythereof.

Heretofore, so far as I am aware, it has been usual to employ a key forholding a separate bearing-piece securely in position in the box, thekey and bearing-piece being made in two distinct parts and connectedtogether in various ways. I

The object of the present invention is to simplify the construction ofthe car-axle bearings by casting the key and the bearing-piece in oneintegral part and of such a character that it may be changed in itsdetails of construction to adapt it to boxes and brasses of diiferentkinds.

In the accompanying drawings I have illustrated the invention in asimple form, referring to which--- Figure 1 is a longitudinal sectionalview of a car-axle box embodying my invention. Fig. 2 is a bottom planview of the key. Fig. 3 is a detailed enlarged sectional view of one endof the key.

Referring to the drawings, in which like letters of reference denotecorresponding parts in all the figures, A designates the journalbox,which may be of any well-known construction, the particular formillustrated being employed by me here simply for the purpose of showingthe application of the invention. The brass O is arranged within the boxto engage the axle Bin the usual manner, and this brass has heretoforebeen maintained in its proper relation to the axle by means of aseparate bearing-piece interposed between the brass and a key securedwithin the box and having a certain freedom of movement in the key; butby my present invention the brass is held in its proper position by mypeculiarly-formed key D. This key consists,

preferably, of a substantially fiat plate provided with side lugs F toengage correspond ing lugs inside of the box and a projection orsecuring the key in place.

heel G, which engages the lug H on the inner side of the top of the box.The manner of securing the key within the box by means of theaforementioned lugs islcommon in the art,

and it will be understood, of course, that I do not limit myself to anyparticular method of As I have heretofore stated, the particularconstruction of the details of my improved key may be varied as desired,the essential feature of the invention comprising a key provided with anintegral bearing-surface to engage the brass, and this bearing-surfaceis preferably of a circular concave form to accommodate thecorresponding circular convex bearing-surface of the brass. It isobvious that the edges of the concaved bearing-surface may be extendedbelow the lower face of the adjacent portions of the key or they may beflush therewith, as desired, and other changes in the details ofconstruction may be made without departing from the spirit orsacrificing the advantages of the invention. It will thus appear that bycasting the key and the bearing-surface which engages directly with thebrass in one piece I reduce the number of parts necessary in thecar-axle bearing and avoid all the disadvantages of a number of workingparts which have heretofore been connected together in various ways andwhich are liable to become bound in wrong positions and otherwise getout of order.

In the drawings I have shown the brass provided with a convexbearing-surface and the key with a corresponding concave bearingsurface;but I do not limit myself to this particular arrangement, for it isobvious that the brass may have the concave bearing-surface and the keyprovided with the convex bearwhat I claim as new, and desire to secureby movementin any direction andalateral move- Letters Patent, is ment,one Within the other, substantially as In a car-axle box, thecombination with 21, described. brass having a circular convexbearing-sur- Signed at New York, in the county of New I5 5 face on itsupper side, of a key adapted to be York and State of New York, this 26thday of secured Within the box and provided on its August, A.
